Abstract

Multi-view video switching control methods and systems are disclosed. It is determined whether a VBI (vertical blanking interval) of signals respectively transmitted by a first GA (graphic array) and a second GA is detected. The video source of first and second GAs belongs to the same first video source. If the VBI corresponding to first GA is detected first, the video source of first GA is switched to a second video source, and the video source of second GA is switched to the second video source if the VBI corresponding to second GA is then present. If the VBI corresponding to second GA is detected first, the video source of second GA is switched to the second video source, and the video source of first GA is switched to the second video source if the VBI corresponding to first GA is then present.

Description

    BACKGROUND
  • The present disclosure relates generally to video display, and, more particularly to control methods and systems that efficiently switch displays in a multi-view environment.
  • With the advance of information technology, computer systems provide multiple screen display functions, such as a DuoView technique. In DuoView, a computer system uses two graphic arrays (GAs), such as integrated graphic arrays (IGAs) to fetch and play back a single video source in different timing.
  • Additionally, in image rendering, a Flip (video switching) technique is used to enhance the rendering speed, and avoid display of rendering procedure. In Flip, an image is pre-rendered and stored in a specific rendering buffer, and after the image has been rendered, a rendering buffer originally accessed by a graphic array is switched to the specific rendering buffer comprising the new rendered image during an information notification interval, such as a vertical blanking interval (VBI) of message transmission.
  • In the DuoView environment, the conventional Flip technique must detect the vertical blanking interval of signals transmitted by a specific graphic array, and switch the video source in the interval. After the video source of the specific graphic array is switched, the vertical blanking interval of signals transmitted by another graphic array is then detected, and the video source is switched in the interval. FIG. 1 is a timing diagram illustrating an example of multi-view video switching control. As shown in FIG. 1, it is assumed a direction of video switching is received at T1. In this example, after the vertical blanking interval of signals transmitted by GA1 is detected at T2, the video source of GA1 is switched in the interval. Thereafter, at T3, the video source of GA2 is switched if the vertical blanking interval of signals transmitted by GA2 is detected. Conventionally, since a specific graphic array must be specified, the video switching can take a maximum of an additional whole cycle to complete.
    • SUMMARY
  • Multi-view video switching control methods and systems are provided.
  • In an exemplary embodiment of a multi-view video switching control method, it is determined whether a vertical blanking interval of signals respectively transmitted by a first graphic array and a second graphic array is present. The video source of the first and second graphic arrays belongs to the same first video source. If the vertical blanking interval corresponding to the signal transmitted by the first graphic array is detected first, the video source of the first graphic array is switched from the first video source to a second video source, and it is continuously determined whether the vertical blanking interval corresponding to the second graphic array is present. If so, the video source of the second graphic array is switched from the first video source to the second video source. If the vertical blanking interval corresponding to the signal transmitted by the second graphic array is detected first, the video source of the second graphic array is switched from the first video source to the second video source, and it is continuously determined whether the vertical blanking interval corresponding to the signal transmitted by the first graphic array is present. If so, the video source of the first graphic array is switched from the first video source to the second video source.
  • An exemplary embodiment of a multi-view video switching control system comprises a first graphic array, a second graphic array, and a processing module. The first and second graphic arrays transmit signals from a first video source. The processing module detects a vertical blanking interval of signals respectively transmitted by the first graphic array and the second graphic array. If the vertical blanking interval corresponding to the signal transmitted by the first graphic array is detected first, the processing module switches the video source of the first graphic array from the first video source to a second video source, and continuously detects the vertical blanking interval corresponding to the signal transmitted by the second graphic array. If the vertical blanking interval corresponding to the signal transmitted by the second graphic array is detected, the processing module switches the video source of the second graphic array from the first video source to the second video source. If the vertical blanking interval corresponding to the signal transmitted by the second graphic array is detected first, the processing module switches the video source of the second graphic array from the first video source to the second video source, and continuously detects the vertical blanking interval corresponding to the signal transmitted by the first graphic array. If the vertical blanking interval corresponding to the signal transmitted by the first graphic array is detected, the processing module switches the video source of the first graphic array from the first video source to the second video source.
  • Multi-view video switching control methods may take the form of program code embodied in a tangible media. When the program code is loaded into and executed by a machine, the machine becomes an apparatus for practicing the disclosed method.

  • The multi-view video switching control system 200 comprises a frame buffer 210, graphic arrays (GAs) 221 and 222, and display devices 231 and 232. It is noted that, while a dual-view environment is disclosed in this embodiment, the invention is equally applicable to any multi-view environment.

  • FIG. 3 is a flowchart showing an embodiment of a multi-view video switching control method.
  • In step S301, a direction for video switching is received. In step S302, the information notification interval, such as the vertical blanking interval of signals respectively transmitted by the first and second graphic arrays, is detected. The video source of the first and second graphic arrays is the same as a first video source.
  • In step S303, it is determined whether the vertical blanking interval corresponds to the first or second graphic array.

In step S310, it is determined whether the vertical blanking interval corresponding to the first graphic array has been detected. If not (No in step S310), the procedure remains at step S309. If so (Yes in step S310), in step S311, the video source of the first graphic array is switched from the first video source to the second video source.
  • FIG. 4 is a timing diagram illustrating an embodiment of an example of multi-view video switching control. Compares to FIG. 1, in this embodiment, the vertical blanking interval of signals transmitted by GA2 is first detected at T4, and the video source of GA2 is switched. At T5, the vertical blanking interval of signals transmitted by GA1 is detected, and the video source of GA1 is switched, shortening the time for video switching. The multi-view video switching control methods and systems of the invention thus provide an efficient mechanism for switching displays in the multi-view environment.
  • Multi-view video switching control methods and systems, or certain aspects or portions thereof, may take the form of program code (i.e., executable instructions) embodied in tangible media, such as floppy diskettes, CD-ROMS, hard drives, or any other machine-readable storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine thereby becomes an apparatus for practicing the methods. The methods and apparatus may also be embodied in the form of program code transmitted over some transmission medium, such as electrical wiring or cabling, through fiber optics, or via any other form of transmission, wherein, when the program code is received and loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the disclosed methods. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique apparatus that operates analogously to application specific logic circuits.
